LUBRICATOR FOR STEAM MACHINERY.

SPECIFICATION forming part of Letters Patent No. 366,714, dated July 19,1.887.

Application tiled April i6, 1887. Serial No. 235,037. (No model.)

To (all whom it may concern:

Be it known that I, 'GEORGE Z. CLARK, of Topeka, inthe county of Shawneeand Si ate of Kansas, have invented certain new and useful Improvementsin Lubricators for Steam Machinery, of which the following is aspecification, reference being had to the accompanying drawings,illustrating my improvements, in which- Figure l is a verticalccntralsectional view of my improved device, and Fig. 2 is a similarview showing a formal modification.

The object of my invention is to provide a simple, reliable, economicallubricator, to be operated by the use otsteam, and which may be attachedto a steam-cylinder or other parts of steam machinery requiring internallubrication.

Referring to the letters upon the drawings, A designates an oil-cup,open and internally screw-threaded at both ends.

I3 designates a cock or faucet, of ordinary character, lfor draining offthe water of con densation.

O designates a cross-piece or guide for one end of the oil-tube D,supported in the screwthreaded opening X, to hold the tube in ils place.

E designates a cap, which screws over the top of the oil-cup, fittingsteam-tight. There is a screw-threaded opening through this cap, intowhich fits the pointed screw-pin F, the point of the pin entering anopening in the upper end ot' the oil-tube D. This oil tube has anenlarged end or collar, L, at the bottom, having its seat made tightwith a ground joint at M, in the ordinary way.

G designatesanut, which screws down upon the top ol the'cap E, and litstightly around the smooth partof the pin F.

II is a plug or stopper for the lower end of the oil-cup, whichsc'rewsinto it, as illustrated. This plug is externally screw-threadedat I on its lower end for the purpose of attaching the lubrieator to asteam-cylinder or other part to be internally lubricated.' It is alsointernally screw-threaded to receive the nut K. The oil-tube beinginserted from the bottom in place, the nut K is screwed up, so as topress the enlarged end of the tube irmly and steamtight against its seatat M, so that the opening through the nut will form a continuationoit'the oil-tube. To supply the cup with oil, the top cap, E, holdingthe pin, should be unscrewed, so as to permit oil to be poured in at theopening X and partly till the oil-cup, as indicated. rIhen the cap Eshould be screwed down, and the pin F should be adjusted to admit moreor less oil into the tube D, according to the amount ot lubricationdesired. rlhcn, when steam is on, it will enter through the nut K,through the tube D, and pass into the upper part of the oil-cup, whereit will condense, and the water ot condensation will settle to thebottom of the cup, raising the oil to the top, where it will overflowaround the point of the pin into the oil tube and drip down through itto t-he interior of any machinery to which the lubricator may beattached.

In Fig. 2, where a modification of my lubricator is shown, the plug H isinternally screwthreaded at its upper end at N, and a steamtight jointis formed at O, the position of the enlarged end ofthe oil-tube beingreversed, so that it will lit down upon the seat at O, as shown. Theplug II is internally screwthreaded at its upper end to receive the nutQ, which forces the enlarged end L of the tube down on its seat. This isa formal change, in which I also use a nut with a hole through it forforcing the tubeto place upon its seat.

I am aware that it is not new to lubricate machinery internally byraising oil and dripping it through the process of condensing steamwithin an oil-receptacle, and I do not claim that, but

Vhat I el'aim,and desire to secure by Letters Patent of theUnitedStates, is-

In a lubricator for steam machinery, the combination, with an oil-cup,A, open at both ends and provided with screw-threaded stoppers, of theoil-tube D, provided with a collar or enlarged lower end seatedsteam-tight upon the plug II, a nut with an opening through it forsecuring the tube firmly to its seat, the pointed screw-pin F, toregulate the iiow of oil into the tube D, and the nut G, substantiallyas set forth.

In testimony whereof I have hereunto subscribed my name. i

GEORGE Z. CLARK.
